If the grub in sda6 is working, you can directly use it's menu.lst.

Boot to grub4dos command line.

in it type

CODE

find --set-root /menu.lst

[ENTER]
provided that you have in ROOT of the sda6 the menu.lst file (if you have it in, say, /boot/menu.lst change line accodingly)

grub4dos should find the file allright (of course if you have several partitions with file menu.lst you may want to temporary rename the "other" ones).

now type:

CODE

root

[ENTER]
grub4dos will reply with the partition in grub4dos notation, probably (hd0,5)
Now, simply issue the command:

CODE

configfile (hd0,5)/menu.lst

[ENTER]

The find command reports my grub4dos menu.lst, hd0,0, not the linux grub menu.lst.

Really?

Really?

Haha, oops

[Alexnharvey]

Ok. So if I rename Grub4dos-menu.lst, reboot. Then I try to boot ubuntu8.04.4-menu.lst. If it works, great, but if it didn't how would i restore function to grub4dos, using a livecd to rename menu.lst again?

Thanks

If booting of the ubuntu does not work, from grub4dos command line (say that you have renamed menu.lst on (hd0,0) to mymenu.lst) you run:

CODE

configfile (hd0,0)/mymenu.lst

and you boot whatever you were booting before.

But you can leave menu.lst alone and create a file on the same partition where the ubuntu menu.lst is, say mytagfile.tag.

CODE

find --set-root /mytagfile.tag

CODE

root

(take note of the feedback from grub4dos, let's say it is (hd0,5), then

CODE

configfile (hd0,5)/menu.lst

It was just a way to make sure you get the right hard disk and partition.

There are several other ways, I thought this to be an easy one.

Thanks. So if I were confident of the device, eg hd0,5, i could go ahead and specify it and try to boot.

with

CODE

root (hd0,5)
configfile hd0,5/menu.lst

I have to be cautious because if I am unable to boot XP again, like I was after my ubuntu9.04 install, I will be in trouble with my wife.

Yep, and NO.
Yes, but you can check the device easily.
In grub4dos command line

CODE

root (hd

[TAB]
will give you the opportunity to see currend hd's

Try

CODE

root (hd0,1)

[ENTER]
then (hd0,2), etc.

then:

CODE

configfile /

[TAB]
will list the files on that partition, so that you can make sure it is the right one....

Once you have established root, you do not need to re-specify the hd partition, you can use a relative path.

And NO, (hd0,5) is ALWAYS between brackets.

Thanks a lot, I got it booted. Now have to fix the wireless connection.
